Volume2: Online security: Your architectural requirements.
In Connectikpeople we are very conscious regarding the online security stakes
.Therefore we have decided via this series to highlight some convenient like to
help you.
Some systems operate better in highly distributed environments, on large
networks or in small environments. At Concord Hospital, one BigFix server
manages 4,700 PCs and 400 servers, Starry says, although the system can scale
to 250,000 endpoints. Colville agrees that a strength of BigFix is its
scalability. "It can play in very large or very small organizations."
Meanwhile, at HPD, Jacob needed a system that could stretch across multiple
distributed points. HPD was able to distribute Lumension servers in five
boroughs in New York City, with the main server at the primary data center in
downtown Manhattan. "Endpoints are able to pull from a distributed point
that's the shortest hop away and sometimes even in the same building as the PCs
are located," he says.
At Tamiyasu, Bradley liked the fact that Shavlik was "nimble and
lightweight. Others are very enterprise-tailored," she says. "I
couldn't dedicate the database and hardware resources required."
DON'T expect to "set it and forget
it." According to Jacob, just because you hear the word "automation"
doesn't mean you can click "enable" and let the system do the rest.
In addition to creating a careful and thorough test methodology, "you have
to tweak, control
and plan deployments and do compatibility testing," he says. For instance,
when you look at a report that shows a certain number of patches didn't get
applied, you need to see why that happened and then redeploy them. At HDS, one
engineer is a dedicated Lumension administrator, managing the deployments,
tests, feedback and remediation actions, Jacob says. "I would say 30
percent to 40 percent of his time is devoted to the patch management
process," he says. "It does require man-hours, as well as always
keeping risk in perspective."
DON'T overlook testing. The vendors perform some internal testing before bundling up and
distributing patches. However, this is mainly focused on determining whether
the patch breaks standard software and verifying that it does what it claims to
do, Maiwald says. For example, Starry says, BigFix provides quality assurance
on the patches before releasing them. "If a patch is issued on Patch
Tuesday, it's in our hands by midnight or 1:00 a.m. or 2:00 a.m.," he says.
Patch Tuesday is the second Tuesday of each month when Microsoft releases its
patches.
This does not, however, take the place of regression testing you'll need to
do on-site, Maiwald says. "The vendor doesn't test all the possible
permutations of what is going to happen when it's applied." The stakes get
higher as the environment grows. "It's one thing to push a patch out to 10
clients, but it's a bigger deal with 1,000 or 10,000," he says. Each
enterprise needs to determine the level of testing required for different
situations, Maiwald says, as well as the level of change management needed. From
